‘But YHWH sent out a great wind on the sea, and there was a mighty tempest on the sea, so that the ship was likely to be broken.'
But YHWH was not going to let Jonah off so easily. Jonah was His servant and He never just cast off His servants however badly they behaved. He was as concerned to show mercy to Jonah, as He was to the sailors and to Nineveh. So He sent a great wind on the sea, and aroused a mighty tempest on the sea, so that the probability was that the ship would be broken in pieces. It does not sound like an act of love, but it was. How often He also break up our foundations so that we might learn to walk in His ways and trust and obey Him.
